Zebrafish Injectable Plastic for Identification Tagging (ZIP IT) for larvae to adults using a fluorescent Visible Implant Elastomer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Distinguishing individuals or small groups is essential for many experiments. The regenerative properties of zebrafish make traditional marking methods for rodent models (e.g., tattoos, tissue clipping) ineffective. Fluorescent Visible Implant Elastomer (VIE) can permanently mark juvenile and adult zebrafish but to date no marking technique has been described for larval stage zebrafish. This protocol, Zebrafish Injectable Plastic for Identification Tagging (ZIP IT), utilizes VIE in zebrafish as early as 2 days post fertilization (dpf) using standard microinjection methods and direct injection using an insulin syringe at one month. Larval zebrafish between 2 and 7 dpf were injected in the dorsal musculature. At one month, retention and visibility of the VIE was observed in 72% of the injected fish with no effect on growth; however, a variable change in mortality was observed, generally higher than the uninjected fish. This demonstrates that VIE can be used in very early stages of fish development, providing the first procedure to track individuals or groups within a larger population. Subcutaneous injection of juvenile zebrafish starting at one month has greater than 99%-mark retention and visibility with very low mortality. The combination of larvae and juvenile VIE injections also provide a powerful tool to track and gather data from marked fish throughout their lifespan.•We present a method for tagging individuals or groups of zebrafish at most life stages (larvae or juvenile/adult) with Visible Implant Elastomer (VIE).•The larvae and juvenile injection procedures can be combined so that an individual fish can be tagged for its entire lifetime. Larvae injections become significantly less visible after one month; however, the fish can be reinjected using the juvenile procedure, thus allowing continuity of the visible mark.•This protocol was empirically built on the "Evaluation of VIE tags in Zebrafish (
